After I applied, I had a telephone interview and was invited to a one day assessment center.Including one roleplay, we had to discuss a problem and to present our solution to our project manager. The single interview has been like every other interview and maybe is the crucial part of the whole process. One written test was done, but I do not think it was important. The verbal test was about to explain a method to the recruiter. A lot of waiting time, but in a nice atmosphere, prospects are valued, at least they made us to think so. Only a few were rejected at the end
